About
GAMMA Polymer Distribution Line Post Insulators provide superior support and electrical insulation on overhead distribution lines, conductor jumpers or leads. They can be installed horizontally or vertically on metal, concrete or wooden structures.
The core of the insulator is made of a corrosion resistant epoxy resin fiberglass rod constructed exclusively for electrical and mechanical applications. Housing and sheds consist of a one-piece injection molded composite material that chemically bonds to the core rod. This creates a water-tight seal between the polymer and the rod that is impervious to moisture penetration.
The composite material itself is made of silicone rubber with additives to enhance performance in polluted enviroments and under a variety of conditions such as rain, ice, sand and salt.
The line end of GAMMA's Polymer Line Post Insulator is available in two configurations: Hot Dip Galvanized Iron Casting or Porcelain. The porcelain end fitting provides superior leakage distance and reduced unit weight. Both are sealed to prevent water from penetrating to the fiberglass core
GAMMA Polymer Line Post Insulators are designed, manufactured and tested according to ANSI standard C29.18.
